A grammar mistake present in an included screenshot was pointed out to me, an instance of text being incorrectly displayed was fixed and the text 'Return to Game,' which was previously untranslated on the save screen was changed.
This is a hack of Sonic the Hedgehog for the Sega Genesis. It alters the palette, layout, and names of each level. Bosses are made harder. Level select only allows the choice of the first act of each level. There are few full level layout hacks for this game so it’d be a good idea to give this hack a try.
The patch is in xdelta format. The ROM should be in BIN format.
